edit this plugin to allow for never ending comment editing WordPress

SOLVED

Looking to have the plugin below edited (preferably via a function I can put in my theme's function.php so that the time limit for comment editing is completely removed/never-ending.

At the moment it only allows for editing up to 90 minutes (despite using a longer time) using the function...
// SCE comment edit time
add_filter( 'sce_comment_time', 'edit_sce_comment_time' );
function edit_sce_comment_time( $time_in_minutes ) {
return 514000;
}

Please show all changes you made so I can replicate them should the plugin need updating.
